Application filed December 22, 1913. Serial No. 808,236.

To all whom it'may concern:

Be it known that we, CHARLES SMITH CFKLLINER and JOSEPH ALBERTCIIALLINER, subjects of the King of Great Britain and Ireland, andresidents of Manchester, in the county of Lancaster, England, engineers,have invented certain new and useful Improvements in MetallicVVheel-Spokes, of which the following is a specification.

Our invention relates to improvements in the construction of sheet metalwheels for motor road and other vehicles that is to say, to that classin which the rim, spokes and hub are made fromone or more parts of sheetsteel or the like assembled together and secured by a welding or brazingprocess at the contiguous joints.

1 Our invention will be fully described with reference to theaccompanying drawings in which F igure l is a plan view of a blank fromwhich each spoke is made, Fig. 2 front elevation of a spoke, Fig. 3 planof same, Fig. 4 back elevation and F 1g. 5 side elevation,

Fig. 6 front elevation showing the spokes assembled together and welded,Fig. 7 sectional plan on lines 1-2 of Fig. 6.

In accordance with our invention we construct each spoke from a. sheetmetal blank a, Fig. 1 adapted at its inner end I), when bent to properform, to constitute a portion of the center or hub c of the wheel, asshown in Fig. 6 so that when the whole of the spokes a are securedtogether a homogenous center or hub will be formed. In other words theinner end of each spoke in blank form is provided with a central portiond and with two side portions 6 splayed out so that when the blank isbent to the required shape of the spoke the central portion forms thefront and the splayed por tions the back of a wedge-shaped portion fwhose edges 9 are on substantially radial lines. The longitudinal jointIt in the spoke is arranged at the back so that it is entirely out ofsight. Reinforcing rings 7: are secured in the hub portion 0 as shown inFig. 7, when desirable, and bolt holes m are provided for securing aspindle hearing or sleeve of approved construction in the hub portion.

The spoke blanks a are formed to give a curved shoulder a where theyjoin each other on the radial lines previously referred to and also togive a curved surface between the spokes from front to back so providinga strong and neat construction. The spokes are welded electrically orotherwise on their longitudinal joints h at the back and likewiseon theradial joints h so providing a complete hub center and leaving only thewelded joints visible from front to back between the spokes.

What we claim is:

In a device of the class described, spokes formed of sheet metal, eachspoke having at one end portion three wedge-shaped tangs, one tang beingarranged at one side of the spoke and being as wide as the remainingtangs together which are arranged at the other side of the spoke, theadjacent edges ofthe wide and narrow tangs of each spoke being securedto the corresponding edges of the wide and narrow tangs of the twospokes on each side of it, and the said spokes being secured together bytheir said tangs and arranged so that they radiate from a common center.

In testimony whereof we have hereunto set our hands in the presence oftwo witnesses.
